Subject: [PATCH] dpaa_eth: enable NETIF_MSG_HW by default

From: Maxim Kochetkov <fido_max@...ox.ru>

When packets are received on the error queue, this function under
net_ratelimit():

netif_err(priv, hw, net_dev, "Err FD status = 0x%08x\n");

does not get printed. Instead we only see:

[ 3658.845592] net_ratelimit: 244 callbacks suppressed
[ 3663.969535] net_ratelimit: 230 callbacks suppressed
[ 3669.085478] net_ratelimit: 228 callbacks suppressed

Enabling NETIF_MSG_HW fixes this issue, and we can see some information
about the frame descriptors of packets.
